Arc faults not only reduce the efficiency and reliability of the PV power generation system, but also may cause safety risks such as fire, which poses a threat to the safe and reliable operation of the PV system. Therefore, timely and accurate diagnosis of PV inverter arc faults is crucial.
Photovoltaic inverters, as key devices, play an important role in converting DC energy to AC energy. However, arcing faults may occur due to aging, damage, or poor contact of components inside the inverter.
Detecting these faults in advance is therefore vital, as it can inform the user of the failure of a PV system or directly shut down systems or components , . Consequently, an additional reliable detection device for DC series arc fault is crucial, least of all the rooftop PV systems.
The power supply system provides energy for the normal operation of the detection system. Hardware structure. The controller is the core of the DC series arc detection device, where its processing speed significantly impacts the system's response time and the speed at which DC series arc faults are identified.
This article introduces an integrated DC arc model, comprising steady-state impedance, high frequency characteristics, and dynamic characteristics. The proposed model can be applied to simulation research on the DC arc faults under complex conditions and to expand the dataset of the DC arc faults in multiple scenarios.
